BZY100 & BZY200 surface tensiometers used to test the surface and interfacial tension of liquid samples, use two measurement methods and built-in data memory, so they can be used independently to meet the needs of various purposes. The instrument is lightweight, easy to install, and can be moved quickly.

Applications:

• Oil aging test, especially transformer oil (ASTM D-971)
• Determination of Surfactant Effectiveness in Wetting Agents and Cleaners Test Surfactant Solution Concentration.
• Canning approval and cleaning validation in the food industry.
• Interfacial tension measurements for quality control and optimization of emulsifiers.
• Cooling lubricant surface tension test.

Features:

▇Using a 4.3-inch touch screen, all operations and information are completed or displayed on the screen.

▇ It can be used to measure the surface interfacial tension of liquids.

▇ Simple and fast operation.

▇ Automatic measurement with high repeatability can be achieved for the set measurement conditions.

Technical Parameters:

Ring size: Pt wire radius is 0.185mm, ring radius is 9.55mm, ring circumference is 60mm.

*Note: The plate/ring test method needs to be specified when ordering. The standard configuration is to choose one from the other.

If the budget is sufficient, it is recommended to configure both the plate and the ring.

**Note: The printer is not included in the standard configuration, please purchase it as required.
